The Velocity Dyad is a tough, no frills, 700c commuting/touring/tandem rim available in 32, 36, 40, and 48 holes in either black or silver finish, with or without machined sidewalls. At 24mm, it’s slightly wider than your typical touring rim (some people even use them on 29′er mountain bikes). With its boxy cross-section, the Velocity Synergy looks more traditional, but the Dyad’s V-shaped cross-section makes the rim stronger and eliminates the need for eyelets. The 36-hole version laced to any decent hub makes a completely bomb-proof commuting wheel. Get the version with machined sidewalls for bump-free braking. Great stuff.
